intersects at a right angle, creates a right angle.

a point that divides a line segment into two ≅ segments.

pair of angles that are adjacent and supplementary.

if vertical angles, then they are congruent.

also equal in measure

divides into two ≅ angle

line, segment or ray that divides a segment at the midpoint

a point that divides a line segment into two ≅ segments

two angles that add up to 180˚

two angles that add up to 90˚

pair of angles that are adjacent and supplementary

Angle measures exactly 90˚

intersects at a right angle, creates a right angle

if vertical angles, then they are congruent

If B is between AC on a line segment, then AB + BC = AC

If T is in the interior of ∠ABC, then m∠ABT + m∠TBC = m∠ABC

all right angles are congruent

two angles complementary to the same angle or congruent angles are congruent

two angles supplementary to the same angle or congruent angles are congruent
